Once the requirements have been identified, grouped, and prioritized, a document known as the software requirement specification is generated. This document describes the intended purpose, requirements, and nature of the software that needs to be developed.

The software requirement specification (SRS) will describe the following information:

• The intended purpose of the applications
• The conventions that are used in the document that are specific to the business process of the organization
• The features of the application
• The user classes who will be using the application
• The environment in which the application will operate
• The functional and nonfunctional requirements of the application

Once the SRS has been generated, it is sent for review and further negotiations. Once they are successfully completed, the application moves into the design phase, where an application mock-up is devised.
